Materials & Manufacture

A513 mechanical steel tubes shall be manufactured via electric resistance welding, and shall be made from hot- or cold-rolled steel, as specified.

Permissible Variations in Dimensions (Wall Thickness)

Permissible variations in wall thickness for A513-1 steel tubing are ±10% of the nominal wall. Permissible variations in wall thickness for A513-5 DOM are available by request. Contact Totten Tubes for more information.
